no. 2 Embodiment approach

[0105] In this embodiment, the forceps joint 88 1 ~88 5 The rotational movement is actively performed so that the shape of the front end portion of the grasping forceps 36 is dynamically deformed following the shape of the forceps channel 35a. That is, the front end portion of the forceps channel 35 a is substantially linear, and the grasping portion 38 for grasping the forceps 36 and the forceps bending portion 40 can be arranged on the linear portion. Moreover, when the nth pliers joint 88 n (1≤n≤5) When it is arranged on the linear portion of the forceps channel 35a, the nth forceps joint part 88 n The rotation angle is approximately 0, and the nth pliers joint 88 n The front end side and base end side of the grasping portion 38 or forceps bending block 86 1 ~86 5 The distance between them is arranged in a substantially straight line. During the pulling action of holding the pliers 36, when the nth pliers joint 88 n When drawn into the pliers channel 35a, the nth pli...

Abstract

An endoscope device having excellent operability. The endoscope device has a treatment device (36, 50) having an operation section to be operated; operation means (48, 62, 80) for operating the operating section; an endoscope (10) having a treatment-device insertion passage into which the treatment device (36, 50) can be inserted, the treatment device (36, 50) being inserted from the proximal end of the treatment-device passage up to the distal end and being able to project from and retract into the distal end; detection means (82, 83, 84, 85) for detecting conditions of that portion of the treatment device (36, 50) which is projected from the distal end of the treatment-device passage; and control means (49, 61, 79) for controlling, based on the result of detection by the detection means (82, 83, 84, 85), operation of the operation section effected by operation of operation means (48, 62, 80).

Description

technical field [0001] The present invention relates to an endoscope apparatus including an endoscope and a treatment instrument inserted into a treatment instrument insertion channel of the endoscope. Background technique [0002] In the currently used endoscope device, the endoscope is inserted into the body cavity, the treatment tool is protruded from the front end of the endoscope through the treatment tool insertion channel of the endoscope, and the treatment is performed in the body cavity through the observation of the endoscope. [0003] In the endoscope device disclosed in Japanese Patent Application Laid-Open No. 9-262241, grasping forceps having a grasping portion capable of being opened and closed at the distal end are used as a treatment instrument. The grasping forceps are introduced into the treatment instrument introduction portion of the endoscope proximal portion, inserted into the treatment instrument insertion channel, and led out from the treatment instr...
